Thank you for your post, and I apologize for the late reply.
Are you still having this issue? If so, are you using the latest FileMaker Pro update (11.0v3)?
Since no other forum member has responded, this would probably be better handled on a one-to-one basis with our Technical Support department, as they can run through several steps and determine different paths to take depending on your answers. You can contact our Technical Support department at toll-free 800-325-2747. If you are outside of North America, please contact the office nearest you.
On the other hand, if you have found a solution, please post here so others can benefit.
